In this Context can also be provided, from such parameter sets for the respective acceptance step. This allows the determination the actual transmission parameters are compressed significantly in time.
  • the present invention is exemplified by an lub interface described in a UMTS mobile network. Without limitation the procedure at other interfaces of a UMTS network or another Communication network.
  • a coarse division is made, i. it will probably be, whether it is a channel of a frame protocol 22, see FIG. 2 or not. In the event that there is no frame protocol 22, it is therefore one NBAP 28 or an ALCAP 26. So it is determined whether it is a specific Channel around a channel for communication between nodes of the transmission system or a channel for communication with at least one participant.
  • a received at the lub interface data stream is after the for the Communication between RNC 14 and Node B 16 or communication with at least decode a UE 18 eligible communication protocol.
  • the decoding is set as soon as with the currently used communication protocol meaningful decoded data or any communication protocols that may be considered did not yield meaningful decoded data.
  • the present channel is used for communication between nodes of the transmission system.
  • the present channel is used the communication with at least one participant.
  • it is therefore a channel of type NBAP or ALCAP, while in the second case the channel represents a frame protocol.
  • the framework to be analyzed is tried by ALCAP or NBAP rules to decode. If decoding errors occur, it could be the other one Act protocol. However, at least NBAP is a complex protocol, the ASN.1 data carries coded by packet encoding rules. A complete decoding would therefore be inefficient and time consuming. This is especially important the UMTS monitoring technology, where the processing speed is a critical Parameter is. In the method according to the invention therefore only a few Evaluated octets of the frame to be analyzed and then a preliminary Decide whether it is an ALCAP or NBAP application. Preliminary decision means that for each selected data packet Points are awarded to either ALCAP or NBAP.
  • the procedure to be performed is in progress therefore, for example, as follows: If the first octet equals an NBAP message type, For example, Initiating Message, Outcome, Successful Outcome or Unsuccessful outcome, then NBAP gets a first point. Is the second octet equal to a valid NBAP method code, e.g. Eg id-RadioLinkSetup, then receives NBAP another point. Is the fifth octet a valid ALCAP message type, ALCAP gets a point. Is the seventh octet available, d. H.
  • the frame length is equal to or greater than seven, and if this octet is a valid ALCAP parameter type, ALCAP gets another point. ALCAP also gets this point if none Message parameters are present, d. H. the frame contains only six octets. Finally, NBAP gets another point if bit 7 or bit 3 in the seventh octet is equal to "1" because these bits are always "0" in valid ALCAP frames (so-called spare bits).
  • the procedure is as follows: under the frame protocol channels There are three downlink data channel types, d. H. Data channels directed towards the subscriber are FACH, PCH and DSCH, and three uplink data channel types, i. Data channels directed to the node, namely RACH, CPCH and USCH, and Although in addition to the DCH, either a downlink, an uplink or a bidirectional Connection can be. Each of these types has a different structure Header and payload, in addition to a large number of transport formats, transport format compilations and logical link combinations.
  • condition 36 see FIG. 4, is not met, d. H. CPCH and / or DSCH frames exist, then the algorithm continues to work in the case of DSCH frames, because DSCH frames have a header size greater than 5 and similar to that DCH type can be separated. Accordingly, after separation of the DCH type Channel types with a header length of four, namely FACH; RACH and PCH.
  • Condition 38 determines whether it is an uplink or a downlink is. If it is an uplink, this channel is of the RACH type. If it is a downlink, the present channel is of type FACH or PCH. With the box 40, the serial number (CFN) is evaluated, in particular the Bit length of the serial number. If these 8 bits are on, it is a channel of type FACH, this has 12 bits, it is a channel of type PCH.
  • CPCH frames it is not possible between CPCH and RACH frames using the algorithm shown in Figure 4, since both have exactly the same structure, but then the knowledge of the mapping of the logical Channels from higher layers, such as MAC or RLC, are used to filter out the required CPCH frames. Similar to the header length, the payload CRC can be used to track the length of the payload frame.
  • the determination of transport formats, transport format compilations or the combinations and modes of the logical channels is much more difficult.
  • the 3GPP specification describes some given configurations and each manufacturer applies certain settings to configure its system. These parameters can be stored in a database. Most of these data are network dependent. Preferably, therefore, a database is designed so that it does not stores only the manufacturer-dependent settings, but also the network-dependent. These databases can be used in accordance with the procedure "Trial-and-error" settings required for correct decoding determine.
  • Another way to determine the transport formats uses the information blocks (SIBs) of the NBAP system, which can be monitored in the NBAP protocol. Both methods, d. H. the use of a database and the use of the SIB information can also be used together to determine the number of Ways to reduce.
  • SIBs information blocks
  • TDD Time Division Duplex
  • CCC Common Control Channel
  • the transport channel has been determined to be of the "RACH” type, the further procedure is shown in Figure 6: If the first two bits equal “0xb00", then the logical Channel of type CCCH, the associated RLC mode is "transparent". At other first two bits is either TDD or a CPCH or no CCCH (Common Control Channel).
  • the star in Figure 6 is intended to indicate that the algorithm presented can not distinguish between RACH and CPCH. Therefore it is possible that one CPCH MAC PDU, whose first two bits are equal to 0xb00, is misinterpreted as a RACH which is mapped to a CCCH.
  • a transport channel from Type PCH no distinction is necessary, see Figure 7, since PCH PDUs no TCTF field to have. A PCH is always mapped to a logical channel of type PCCH and the RLC mode is always "transparent".
  • the length of the RLC length indicator field which is equal to 7 or 15 bits, must be the Frame protocol transport formats are derived. For logical common control Channels, see assumption 2 in the last list of assumptions, will become the RLC used only by the RRC.
